ATTACHMENT FOR DESKS.

SPECIFICATION forming part of Letters Patent No. 406,121, dated July 2,1889.

Application filed November 28, 1888. Serial No. 292,074. (No model.)

To all whom it may concern.-

Be it known that I, HARRY E. ADAMS, a citizen of the United States,residing at NVheeling, in the county of Ohio and State of WVestVirginia, have invented new and useful Improvements in Attachments forDesks, of which the following is a specification.

My invention relates to attachments for desks, the purpose thereof beingto provide a simple and convenient device capable of being attached toand disconnected from a desk,

, and capable also of longitudinal adjustment thereon, whereby the armof a book-keeper may have support, and whereby also a convenient supportis provided for a book, instrument, or other device to be used inconjunction with the book or device lying upon the main portion of thedesk.

The invention is particularly adapted to the use of book-keepers toprovide a rest or support for the arm when entries are to be made uponthe lower portion of the page, in which cases the elbow projects more orless beyond the edge of the desk. and is in the ordinary desk withoutsupport.

My invention consists in the several novel features of construction andnew combinations of parts, hereinafter set forth, an "I then definitelypointed out in the claims.

In the accompanying drawings, Figure l is an end elevation showing myinvention. Fig. 2 is a partial front elevation of the parts shown inFig. 1.

In the said drawings, the reference-n umeral 1 designates a desk of anysuitable form and construction hav ng a desk-top or table 2, which ispreferably sloped in the usual manner. Upon the body 1 of said desk, andupon the front thereof under the desk-top 2, I attach a rail 8,extending from one end of the desk toward the other and parallel withthe projecting edge of the top 2, the rail being attached a shortdistance beneath this projecting edge and provided with a groove orchannel 4 in its upper surface.

The numeral 5 denotes a shelf or support of any desired form and size,to the edge of which is hinged a strip 6, having upon one side a rib '7,adapted to fit in the channel 4 ofthe rail 3. Upon the under face of thesupport is hinged an arm. 8, the free end 00f which is adapted to engagewith a bracketrail 9, attached to the front of the desk at a suitabledistance below the rail 3.

The manner of using the device is evident. 5 5 The end of the strip 6being introduced within the space between the rail 3 and the projectingedge of the desktop, and the rib 7 being placed in the channel. 4, therib is then slid longitudinally upon the rail 3 until the brace S canengage the bracket-rail 9.

The shelf or auxiliary support 5 is then adjusted laterally from time totime, as circumstances may require, the strip 6 sliding on the rail 3and the brace 8 being adjusted on. the bracket-rail 9.

WVhen not in use, the arm 8 may be disengaged from the rail9 and theshelf dropped into the position shown in dotted lines in Fig. 1.

\Vhen once mounted, the auxiliary shelf or support may be readily movedor adjusted to any point upon the front of the desk.

WVhat I claim is-- 1. In a desk or table, an adj ust-able auXiliarysupport consisting of a shelf having a ribbed strip hinged to one edgeand inserted between a grooved rail fastened upon the front of the deskor table beneath the projecting edge of the top, said support beingprovided with a brace or arm engaging with a bracket-rail mounted on thedesk-front beneath the grooved rail, substantially as described.

2. In a desk or table having a top 2, the edge of which projects overthe front of the desk and provided with a grooved rail 3, fastened tothe body of the desk below said projecting edge, a support or shelf 5,having a ribbed strip 6 hinged to its edge and en- 0- gagingin the spacebetween the grooved rail and the projecting edge of the desk, and an arm8 hinged at one end to the under face of the shelf, its other endengaging a bracketrail 9, substantially as described.

-In testimony whereof I affix my signature in presence of tWo witnesses.

HARRY E. ADAMS.
